speaking solely about macs, the cheapest place you could get it works.

warranty is international and you could send it to any authorised apple repair centre.

My favorite Apple Reseller store in terms of service is Ascend Zone @ The Curve, Mutiara Damansara. I've sent in a lot of repairs for my Mac there and the work quality is excellent. Sadly I think they're either closed or have moved somewhere due to slow business.

I think as for right now, EpiCentre The Pavilion provides the best service and customer loyalty programme. They have discounts for accessories for members and also education discounts.

woops, sorry for totally getting your question wrong. i wouldn't be able to vouch for any then as i've not gotten any units locally.

there is a particular establishment that i dislike, on the other hand though
